#1. Field of the Invention

#The present invention relates to devices to facilitate the removal of ashes from ash pits of furnaces or stoves. The problem addressed by such removal devices is that ash normally is extremely lightweight or low in density such that a disturbing of ash produces a floating debris which is difficult to confine and often results in spoiling the surrounding environment such as the living room adjacent to a fire place or wood burning stove. Of course the problem only deals with those types of stoves, furnaces or fire places which do not have their own ash removal conduit therebelow or somewhere therein. However, with most stoves it is necessary to actually remove the ash through an ash door in order to discard the ash as necessary.

#A particular problem arises with this types of stoves and furnaces wherein the combustion chamber and the ash pit are a single location. That is, in some types of stoves or furnaces a grate is utilized which holds the combustible materials at a location elevated with respect to the ash pit. In such stove configurations the ash pit and the combustion chamber are not in the same location, namely, the combustion chamber is immediately above the grate whereas the ash pit is located therebelow. In other types of devices and in particular, wood burning stoves, the ash pit and the combustion chamber are in the same location due to the absence of usage of a grate. It is this type of stove or furnace to which the present invention is directed. This invention does not relate to those types of devices usable with stoves having the coals or combustible materials separated from the ash. The most particular type of device wherein the ash pit and the combustion chamber are in one location is a wood burning stove wherein combustible wood to be burned is placed directly into the ash. With this configuration, the present invention is particularly usable since the tool means includes a rake section having teeth therein which when moved rearwardly will separate coals from the ash. The tool means also includes a hoe section which can, after separation of the ash from the coals, can pull the ash up the inclined ramp into the retaining chamber of the present invention.

Detailed description1,104 words

#The present invention provides a stove ash retaining apparatus 26 which is particularly usable positioned extending through the ash opening 22 thereof. A wood burning stove or furnace 10 normally includes an ash pit 16 which also functions as the combustion chamber. That is, with such a stove 10, there is no grate and as such the ashes 12 accumulate in the same area or locations as the coals 14 or other combustible material utilized for burning. With such configurations, it is conventional to include an air inlet 18 which provides a source of oxygen for combustion and an outlet flue 20 for the formation of the necessary chimney draft to insure continuous combustion.

#The present invention provides an apparatus 26 which is particularly adapted to extend through the ash removal door 24 of the stove 10. The portion of the apparatus 26 which actually extends through the door would be the inclined entry ramp 42.

#Ramp 42 is connected to the housing means 28 of the apparatus 26. Housing means 28 includes a floor means 30 and sidewall means 32 extending upwardly therefrom on opposite edges thereof. Housing 28 also includes a top means 34 extending between the upper edges of the sidewalls 32 and an end means 36 which closes one end of the housing to thereby define an ash retaining chamber therein. The end of the chamber 40 opposite from the end means 36 is open to provide an open end 38 to allow ash to be admitted therethrough.
